BJP MP Nishikant Dubey today said that the expulsion of Trinamool's Mahua Moitra from the parliament gave him pain and it wasn't a happy day for him. Nishikant Dubey said, "The expulsion of a parliamentarian for corruption and on the issue of national security gives me pain. Yesterday, was not a happy day, but a sad day." Ms Moitra, 49, was expelled from Lok Sabha on Friday after the parliamentary Ethics Committee found her guilty of taking bribes in exchange for criticising the government.
